Application December 13, 1947, Serial No. 791,521

4 Claims. 1

My invention relates to universal golf club heads.

An object of my invention is to provide a universal or all-purpose golfclub head, the. sides of which are so formed as to provide the correctangle of striking surfaces to permit the said universal golf club headto be used, in turn, as a driver, a lofting iron, or a putting iron.

A further object of my invention is to provide a universal golf clubhead, the two sides or faces of which are identically but oppositelyformed so that the club may be used by either right-handed orleft-handed golfers.

A still further object of my invention is to provide a universal golfclub head which, being formed of one piece of metal, may be economicallyproduced in large quantities.

Other objects and advantages embraced in my invention will be furtherdisclosed in the ensuing description and the accompanying illustrations,in which:

Figure 1 is a top view of my invention.

Fig. 2 is a side elevation of my invention looking in the direction oflines 2--2 on Fig. 1.

Fig. 3 is a heel end view of my invention looking in the direction ofline 3-3 on Fig. 2.

Fig. 4 is a toe end view of my invention looking in the direction ofline 44 on Fig. 2.

Fig. 5 is a cross-sectional view of my invention taken substantially online 55 on Fig. 2.

Fig. 6 is a cross-sectional view of my invention taken substantially online 6-6 on Fig. 2.

Fig. 7 is a cross-sectional view of my invention taken substantially online 'l'l on Fig. 2.

Referring to the illustrations, my invention is generally designated 8,and consists of a wedgeshaped body portion 9 of a non-corroding metal ofsuitable weight. The narrower top edge ll] of the body 9 is sloped andtapered from the heel l2 to the toe It. The identical but oppositelyformed sides or faces IE flare outwardly toward the bottom M, which isof slightly arcuate formation, so as to be in conformity with the arc ofthe swing of the club.

The said bottom I4 is wider than the top edge ill, and tapers from thetoe 13 to the heel [2, as opposed to the said top edge Ill which tapersfrom heel I2 to toe I3. The oppositely disposed tapered surfaces of thetop edge It! and the bottom surface [4, together with the flared facesl6, provide a progressively changing cross-sectional shape to body 9,ranging from a generally triangular shape at the toe l3, as shown inFigs. 3 and 4, to a generally trapezoidal cross-sectional shape at heell2, as shown in Figs. 3 and 5. The surfaces It are partially conical inconfiguration from toe to heel.

In side elevation, as shown in Fig. 2, the toe 3 may slope outwardlyfrom top to bottom, and he heel l2 may be formed into an S-shape.

A tapped attaching hole ll is bored from a. beveled attaching point II,downwardly through the body 9 at about a 30 angle from the vertical, asshown in Fig. 2, thus providing the correct attaching angle with thegolf club shaft l8 as shown in phantom lines. The two faces I6 aredivided into a heel section [9, a center section 28, and a toe section2|. Fig. 5 illustrates a cross-sectional view of heel section l9 showinga golf ball 22 being contacted by striking point 23 at an angle suitablefor putting. Fig. 6 shows a cross-sectional view of the center section20, together with a golf ball 22, contacting the striking surface 24 atan angle suitable for driving the said golf ball 22. Fig. 7 is across-sectional view taken through the toe section 2i, and shows a golfball 22 contacting the striking surface 25 at an angle suitable forlofting shots.

It will be noticed from the fragmentary phantom line view of a golf ball22 in each of the views 5, ii, and 1 that each of the above-describedgolfing shotsdriving, lofting, and putting may be accomplished byapproaching the golf ball 22 from either the right hand or left handside of the said golf club head 8, so that my universal golf club,inaddition to being adaptable without mechanical adjustment to the threeprincipal types of golf shots-driving, lofting, and putting, may also beused by both left-handed and right-handed golfers.

To use my universal golf club head, it is attached to a golf club shaftI8 of any suitable type. The golf ball 22 is placed in a drivingposition and struck by the center or driving section 29 of golf clubhead 8. For a lofting shot, the toe section 2! is used when addressingthe ball 22. For a putting shot, the heel section l9 contacts the saidgolf ball 22.

Although my invention has been described, the terms used are to bedeemed terms of description rather than terms of limitation, myintention being to retain the right to all mechanical equivalents of thestructural elements depicted, provided they fall within the purview ofthe appended claims.

Having thus disclosed and revealed my invention, what I claim as new,and desire to secure by Letters Patent, is:

l. A universal golf club head comprising, a

wedge-shaped body tapering from the head portion toward the toe portionthereof to form a top portion of triangular cross-sectionalconfiguration and a bottom portion of trapezoidal configuration, thefaces of the said club head being of partially conical and concaveconfiguration formed by generating imaginary geometrical cones withtheir apices at the said heel portion.

2. A universal golf club head comprising, a wedge-shaped body taperingfrom. the, head poi:- tion toward the toe portion thereof to form a topportion of triangular cross-sectional configuration and a bottom portionof trapezoidar configuration, the faces of the said: club; head being ofpartially conical and concave configuration formed by generatingimaginary geometrical cones with their apices at the said heel portion;the said bottom portion being of convex crosssectional configuration.

3. A universal golf club head comprising, a wedge-shaped body taperingfrom the head por-- tion; toward the toe portion thereof to form atopportion of triangular cross-sectional configura tion and a bottom.portion of trapezoidal configuration, the faces of the said club headbeing of partially conical and concave configuration formed bygenerating imaginary geometrical cones with their apices at the saidheel portion, the toprportion of the said golf clubhead having an.angularly formed portion with respect to the base of the said golf clubhead and located at the heel portion to furnish a point of juncture to agolf club shaft, and a thread'ed'opening bored in 4 substantially rightangular relationship to the said angularly formed portion.

4. A universal golf club head comprising, a wedge-shaped body taperingfrom the head portion toward the toe portion thereof to form a topportion of triangular cross-sectional configuration and a bottom portionof trapezoidal configuration, the faces of the said club head being ofpartially conical and concave configuration formed by generating;imaginary: geometrical cones with their apices at the said heel portion,the said bottom portion being of convex crosssectional configuration,the top portion of the said, golf; club head having an angularly formedportion with respect to the base of the said golf el-ulohead and locatedat the heel portion to furnish a point of- ,iuncture to a golf clubshaft, and a threaded opening bored in substantially right angularrelationship to the said angularly formed portion.
